MgCl2
Sodium is Na and Chloride is Cl and their charges balance out so it makes NaCl.
cl-s-s-cl
The net ionic charge on the compound is zero. So if you have two chloride ions (Fe+ Cl- Cl-) the charges will cancel. Thus the formula is FeCl2.
Mg has a +2 charge and Cl has a -1 charge.The correct formula is MgCl2
Potassium chloride, with formula KCl.
Sodium is Na and Chloride is Cl and their charges balance out so it makes NaCl.
cl-s-s-cl
The formula unit of sodium chloride is NaCl; the atomic ratio Na/Cl is 1.Note that the expression molecular formula for NaCl is not correct.
K+ cation and Cl- anion
Back is for salt
The chemical formula of magnesium chloride is MgCl2.
AlCl3 is the correct formula as the valency of aluminium and chlorine are 3 and 1 respectively.
The net ionic charge on the compound is zero. So if you have two chloride ions (Fe+ Cl- Cl-) the charges will cancel. Thus the formula is FeCl2.
Barium chloride has the formula BaCl2.
Mg has a +2 charge and Cl has a -1 charge.The correct formula is MgCl2
Potassium chloride, with formula KCl.
